KGD - WQ - 511 Motor Vehicle Nitrogen Oxides Rapid Detector
Product Introduction
The KGD - WQ - 511 Motor Vehicle Nitrogen Oxides Rapid Detector uses ultraviolet spectroscopy to continuously measure NO and NO₂ in real - time. It is equipped with a Beidou navigation system and an APP software platform, and is specifically designed for rapidly detecting the concentration of nitrogen oxides in the exhaust emissions of in - use vehicles under simulated conditions on a chassis dynamometer or during actual road driving conditions.
